(ii) (A) counsel for the Executive Stockholder (which counsel shall be reasonably acceptable to the Company) shall have furnished the Company with an opinion or other advice, reasonably satisfactory in form and substance to the Company, that no such registration is required because of the availability of an exemption from registration under the Act and (B) if the Executive Stockholder is a citizen or resident of any country other than the United States, or the Executive Stockholder desires to effect any transfer in any such country, counsel for the Executive Stockholder (which counsel shall be reasonably satisfactory to the Company) shall have furnished the Company with an opinion or other advice reasonably satisfactory in form and substance to the Company to the effect that such transfer will comply with the securities laws of such jurisdiction.

Notwithstanding the foregoing, the Company acknowledges and agrees that any of the following transfers of Stock (including, for the purposes of this Section 2(a), Restricted Stock) are deemed to be in compliance with the Act and this Agreement (including without limitation any restrictions or prohibitions herein), and no opinion of counsel is required in connection therewith: (1) a transfer made pursuant to Sections 3 (including transfers in a Proposed Sale (as defined in the Sale Participation Agreement) pursuant to the Sale Participation Agreement), 4 or 5 hereof, (2) a transfer (x) upon the death or Disability of the Executive Stockholder to the Executive Stockholder’s Estate or (y) to the executors, administrators, testamentary trustees, legatees, immediate family members or beneficiaries of a Person who has become a holder of Stock in accordance with the terms of this Agreement; provided that it is expressly understood that any such transferee shall be bound by the provisions of this Agreement, (3) a transfer made after the date hereof in compliance with the federal securities laws to Executive Stockholder’s Trust; provided that such transfer is made expressly subject to this Agreement and that the transferee agrees in writing to be bound by the terms and conditions hereof as an “Executive Stockholder” with respect to the representations and warranties and other obligations of this Agreement; and provided further that it is expressly understood and agreed that if such Executive Stockholder’s Trust at any point includes any Person or entity other than the Executive Stockholder, his or her spouse (or ex-spouse) or his or her lineal descendants (including adopted children) such that it fails to meet the definition thereof as set forth in Section 6(b) hereof, such transfer shall no longer be deemed in compliance with this Agreement and shall be subject to 3(d) below, (4) a transfer of Stock made by the Executive Stockholder to Other Employee Stockholders; provided that it is expressly understood that any such transferee(s) shall be bound by the provisions of this Agreement (in addition to the provisions set forth in an Other Employee Stockholders Agreement to which such Other Employee Stockholders are a party), or (5) a transfer made by the Executive Stockholder, with the Board’s approval, to the Company or any subsidiary of the Company.

(b) The certificate (or certificates) representing the Stock, if any, shall bear the following legend:

“THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED, SOLD, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF UNLESS SUCH TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION COMPLIES WITH THE PROVISIONS OF THE EXECUTIVE STOCKHOLDER’S AGREEMENT AMONG SAMSON RESOURCES CORPORATION AND THE EXECUTIVE STOCKHOLDER NAMED ON THE FACE HEREOF OR THE SALE PARTICIPATION AGREEMENT AMONG SUCH EXECUTIVE STOCKHOLDER AND SAMSON RESOURCES CORPORATION, IN EACH CASE EFFECTIVE AS OF APRIL 18, 2013 (COPIES OF WHICH ARE ON FILE WITH THE SECRETARY OF THE COMPANY) AND ALL APPLICABLE FEDERAL AND STATE SECURITIES LAWS.”

(c) The Executive Stockholder acknowledges that he or she has been advised that (i) the shares of Stock are characterized as “restricted securities” under the Act inasmuch as they are being acquired from the Company in a transaction not involving a Public Offering and that under the Act (including applicable regulations) the Stock may be resold without registration under the Act only in certain limited circumstances, (ii) a restrictive legend in the form

heretofore set forth shall be placed on the certificates (if any) representing the Stock and (iii) a notation shall be made in the appropriate records of the Company indicating that the Stock is subject to restrictions on transfer and appropriate stop transfer restrictions will be issued to the Company’s transfer agent with respect to the Stock.

(f) The Executive Stockholder represents and warrants that (i) with respect to the Purchased Stock and the Option Stock, the Executive Stockholder has received and reviewed the available information relating to such Stock, including having received and reviewed the documents related thereto, certain of which documents set forth the rights, preferences and restrictions relating to the Options and the Stock underlying the Options and (ii) the Executive Stockholder has been given the opportunity to obtain any additional information or documents and to ask questions and receive answers about such information, the Company, the Company Group and the business and prospects of the Company and the Company Group which the

Executive Stockholder deems necessary to evaluate the merits and risks related to the Executive Stockholder’s investment in the Stock and to verify the information contained in the information received as indicated in this Section 2(f) and the Executive Stockholder has relied solely on such information.

(g) The Executive Stockholder further represents and warrants that (i) the Executive Stockholder’s financial condition is such that the Executive Stockholder can afford to bear the economic risk of holding the Stock for an indefinite period of time and has adequate means for providing for the Executive Stockholder’s current needs and personal contingencies, (ii) the Executive Stockholder can afford to suffer a complete loss of his or her investment in the Stock, (iii) the Executive Stockholder understands and has taken cognizance of all risk factors related to the investment in the Stock, (iv) the Executive Stockholder’s knowledge and experience in financial and business matters are such that the Executive Stockholder is capable of evaluating the merits and risks of the Executive Stockholder’s purchase of the Stock as contemplated by this Agreement and (v) if the box next to the Executive Stockholder’s signature is checked, the Executive Stockholder is an “accredited investor” as defined in Rule 501(a) of Regulation D, as amended, under the Act.

3. Transferability of Stock.

(a) The Executive Stockholder agrees that he or she will not transfer any shares of Stock at any time without the consent of the Investors; provided, however, that the Executive Stockholder may transfer shares of Stock pursuant to one of the following exceptions: (i) transfers permitted by Sections 4 or 5; (ii) transfers permitted by clauses (2), (3) and (4) of Section 2(a); (iii) transfers permitted pursuant to the Sale Participation Agreement; (iv) transfers approved by the Board in writing; or (v) transfers to the Company or its designee (any such exception, a “Permitted Transfer”).

(b) Notwithstanding anything to the contrary herein, all transfer restrictions contained herein shall terminate and be of no further force or effect upon the earlier of (i) the occurrence of a Change of Control and (ii) following an Initial Public Offering, the date on which the Sponsors have sold or otherwise disposed of at least eighty percent (80%) of the Common Stock owned, directly and indirectly, by the Sponsors, unless earlier waived by the Company (such earlier date, the “Lapse Date”). For the avoidance of doubt, after the expiration of the time period specified in (i) and (ii) of Section 2(e), the Executive Stockholder shall be able to transfer shares of Stock without regard to any transfer restriction contained herein.

(c) No transfer of any shares of Stock in violation hereof shall be made or recorded on the books of the Company and any such transfer shall be void ab initio and of no effect.

(d) Notwithstanding anything to the contrary herein, the Company may, at any time and from time to time, waive in writing the restrictions on transfers contained in Section 3(a), whether such waiver is made prior to or after the transferee has effected or committed to effect the transfer, or has notified the Investors of such transfer or commitment to transfer. Any transfers made pursuant to such waiver or which are later made subject to such a waiver shall, as of the date of the waiver and at all times thereafter, not be deemed to violate any applicable restrictions on transfers contained in this Agreement.

4. The Executive Stockholder’s Right to Resell Stock and Options to the Company.

(a) Except as otherwise provided herein, if the Executive Stockholder’s employment with the Company Group terminates as a result of the death or Disability of the Executive Stockholder, then the applicable Executive Stockholder Entities, shall, for 365 days (the “Put Period”) following the date of such termination for death or Disability, have the right to:

(i) with respect to Stock, sell to the Company, and the Company shall be required to purchase, on one occasion, all or any portion of the shares of Stock then held by the applicable Executive Stockholder Entities at a per share price equal to Fair Market Value on the Repurchase Calculation Date (the “Section 4 Repurchase Price”); and

(ii) with respect to any outstanding vested Options, sell to the Company, and the Company shall be required to purchase, on one occasion, all or any portion of the vested Options then held by the applicable Executive Stockholder Entities for an amount equal to the sum of the excess, if any, of the Section 4 Repurchase Price over the Option Exercise Price of each Option for all of the Exercisable Option Shares, which Options shall be terminated in exchange for such payment. In the event the Executive Stockholder Entity elects to sell under this Section 4(a)(ii) and the foregoing Option Excess Price on a vested Option is zero or a negative number, such outstanding exercisable Option granted to the Executive Stockholder shall be automatically terminated without any payment in respect thereof. In addition, and for the avoidance of doubt, all unvested Options shall be terminated and cancelled without any payment therefor as of the date specified by the Award Agreement in the event of the Executive Stockholder’s death or Disability (after taking into consideration any accelerated vesting that may occur in connection with such event).

(b) In the event the applicable Executive Stockholder Entities intend to exercise their rights pursuant to Section 4(a), such Executive Stockholder Entities shall send written notice to the Company, at any time during the Put Period, of their intention to sell shares of Stock in exchange for the payment referred to in the applicable subsection of Section 4(a)(i) and shall indicate the number of shares of Stock to be sold and, for purposes of Section 4(a), the number of Options (based on the number of Exercisable Option Shares) to be sold with payment in respect thereof (the “Redemption Notice”). The completion of the purchases shall take place at the principal office of the Company on no later than the fifteenth business day (such date to be determined by the Company) after the giving of the Redemption Notice. The applicable Repurchase Price (including any payment with respect to the Options as described above) shall be paid by delivery to the applicable Executive Stockholder Entities, at the option of the Company, of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Executive Stockholder Entities (or by wire transfer of immediately available funds, if the Executive Stockholder Entities provide to the Company wire transfer instructions) against delivery of certificates or other instruments representing the Stock so

purchased and appropriate documents cancelling the Options so terminated appropriately endorsed or executed by the applicable Executive Stockholder Entities or any duly authorized representative. Notwithstanding anything in this Section 4(b), in the event the Company receives a Redemption Notice at a time when the Fair Market Value is equal to or less than the applicable Option Exercise Price, the Company shall provide the Executive Stockholder Entity that delivered the Redemption Notice to the Company with a statement of valuation and a request that the applicable Executive Stockholder Entity resubmit the Redemption Notice in order to confirm its desire to exercise its rights hereunder with respect to any vested Options.

(c) Notwithstanding anything in this Section 4 to the contrary, if there exists and is continuing a default or an event of default on the part of the Company Group under any loan, guarantee or other agreement under which any part of the Company Group has borrowed money or if any repurchase under Section 4(a) or Section 5 below, as the case may be, would result in a default or an event of default on such part of the Company Group under any such agreement or if a repurchase by the Company would reasonably be expected to be prohibited by the Delaware General Corporation Law or any federal or state securities laws or regulations (or if the Company reincorporates in another state, the business corporation law of such state) (each such occurrence being an “Event”), the Company shall not be obligated to repurchase any of the Stock or the Options from the applicable Executive Stockholder Entities to the extent it would cause any such default or would be so prohibited by the Event for cash but instead, with respect to such portion with respect to which cash settlement is prohibited, may satisfy its obligations with respect to the Executive Stockholder Entities’ exercise of their rights under the applicable subsection of this Section 4 by delivering to the applicable Executive Stockholder Entity a note with a principal amount equal to the amount payable under this Section 4 that was not paid in cash, having terms acceptable to such part of the Company Group’s lenders and permitted under such part of the Company Group’s debt instruments but which in any event (i) shall be mandatorily repayable promptly and to the extent that an Event no longer prohibits the payment of cash to the applicable Executive Stockholder Entity pursuant to this Agreement; and (ii) shall bear interest at a rate equal to the effective rate of interest in respect of the senior notes issued by such part of the Company Group or, if there are no such notes outstanding, a rate equal to the prime rate as published by The Wall Street Journal as of the date of issuance plus 3%. In such cases, the Put Period shall be tolled for so long as an Event shall continue. Notwithstanding the foregoing and subject to Section 4(e), if an Event exists and is continuing for one hundred and eighty (180) days after the date of the Redemption Notice, the Executive Stockholder Entities shall be permitted by written notice to rescind (with the ability to reissue at any time during the Put Period) any Redemption Notice with respect to that portion of the Stock and Options repurchased by the Company from the Executive Stockholder Entities pursuant to this Section 4 with the note described in the foregoing sentence, and such repurchase shall be rescinded; provided that, upon such rescission, such note shall be immediately canceled without any action on the part of the Company or the Executive Stockholder Entities, and notwithstanding anything herein or in such note to the contrary, the Company shall have no obligation to pay any amounts of principal or interest thereunder.

(d) The applicable Repurchase Price shall be paid by delivery to the applicable Executive Stockholder Entities, at the option of the Company, of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Executive Stockholder Entities (or by wire transfer of immediately available funds, if the

Executive Stockholder Entities provide to the Company wire transfer instructions) against delivery of certificates, if any where given to the Executive Stockholder, or other reasonable documents or instruments representing the Stock so purchased and reasonable documents or instruments cancelling the Options so terminated appropriately endorsed or executed by the applicable Executive Stockholder Entities or any duly authorized representative.

(e) Notwithstanding anything in this Agreement to the contrary, except for any payment obligation of the Company which has arisen prior to the occurrence of a Lapse Date, Section 4 shall terminate and be of no further force or effect upon the occurrence of such Lapse Date.

5. The Company’s Option to Purchase Stock and Options of the Executive Stockholder Upon Certain Terminations of Employment.

(a) Termination for Cause by the Company and Breach of Transfer Restrictions. If, (i) the Executive Stockholder’s active employment with the Company Group is terminated by the Company Group for Cause or (ii) the Executive Stockholder Entities intentionally or knowingly effect a transfer of Stock (or Options) that is prohibited under this Agreement (or the Award Agreements, as applicable), after notice from the Company of such impermissible transfer and a reasonable opportunity to cure such transfer which is not so cured (each event described above, a “Section 5(a) Call Event”), then:

(i) with respect to all Options, all outstanding Options (whether vested or unvested) shall be automatically terminated without any payment in respect thereof upon the occurrence of the Section 5(a) Call Event; and

(ii) with respect to any Purchased Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Stock then held by the applicable Executive Stockholder Entities at a per share purchase price equal to the Fair Market Value on the Repurchase Calculation Date; and

(iii) with respect to any Vested Restricted Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Stock then held by the applicable Executive Stockholder Entities at a per share purchase price equal to the Base Price; and

(b) Termination Due to Death or Disability. If the Executive Stockholder’s active employment with the Company Group is terminated due to his or her death or Disability (each, a “Section 5(b) Call Event”) then:

(i) with respect to any Stock acquired by the Executive Stockholder through the exercise of vested Options, the Company may purchase on one occasion all or any portion of the shares of such Stock then held by the applicable Executive Stockholder Entities at a per share purchase price equal to the Fair Market Value on the Repurchase Calculation Date;

(ii) with respect to any outstanding Options, the Company may purchase, on one occasion, all or any portion of the exercisable vested Options held by the applicable Executive Stockholder Entities for an amount equal to the sum of the excess, if any, of the Fair Market Value on the Repurchase Calculation Date over the Option Exercise Price of each Option for all of the Exercisable Option Shares (solely relating to the vested Options being purchased by the Company hereunder), which vested Options shall be terminated in exchange for such payment. In the event the Company elects to repurchase under this Section 5(b)(ii) and the foregoing Option Excess Price on a vested Option is zero or a negative number, such outstanding exercisable vested Option shall be automatically terminated without any payment in respect thereof; and

(iii) with respect to unvested Options, all outstanding unvested Options shall automatically be terminated without any payment in respect thereof as of the date specified by the Award Agreement in the event of the Executive Stockholder’s death or Disability (after taking into consideration any accelerated vesting that may occur in connection therewith).

(c) Termination by the Executive Stockholder Without Good Reason. If the Executive Stockholder’s active employment with the Company Group is terminated by the Executive Stockholder without Good Reason (excluding due to his or her death or Disability) (a “Section 5(c) Call Event”):

(i) before April 18, 2016, then:

(A) with respect to any Purchased Stock, the Company may purchase all or any portion of the shares of such Stock then held by the Executive Stockholder Entities on the date of such termination of employment at a per share purchase price equal to the Fair Market Value on the Repurchase Calculation Date; and

(B) with respect to any outstanding Options, whether vested or unvested, all such outstanding Options shall expire on the date specified by the Award Agreement without any payment in respect thereof; and

(C) with respect to any Vested Restricted Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Stock then held by the applicable Executive Stockholder Entities at a per share purchase price equal to the Base Price; and

(D) with respect to any Option Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Stock then held by the applicable Executive Stockholder Entities at a per share purchase price equal to the lesser of (x) the Base Price and (y) the Fair Market Value on the Repurchase Calculation Date; or

(ii) on or after April 18, 2016, then:

(A) With respect to any Stock, the Company may purchase on one occasion all or any portion of the shares of such Stock then held by the Executive Stockholder Entities on the date of such termination of employment at a per share purchase price equal to the Fair Market Value on the Repurchase Calculation Date; and

(B) With respect to any vested Options, the Company may purchase on one occasion all or any portion of the shares of such vested Options then held by the Executive Stockholder Entities for an amount equal to the sum of the excess, if any, of the Fair Market Value on the Repurchase Calculation Date over the Option Exercise Price of each Option for all of the Exercisable Option Shares (solely relating to the vested Options being purchased by the Company), in each case of the foregoing which vested Options shall be terminated in exchange for such payment. In the event the Company elects to repurchase under this Section 5(c)(ii)(B) and the foregoing Option Excess Price on a vested Option is zero or a negative number, such outstanding vested Option shall be automatically terminated without any payment in respect thereof.

(d) Call Notice. The Company shall have a period (the “Call Period”) of one hundred eighty (180) days from the date of any Call Event (or, if later, with respect to a Section 5(a) Call Event, the date after discovery of, and the applicable cure period for, an impermissible transfer constituting a Section 5(a) Call Event) in which to give notice in writing to the Executive Stockholder of its election to exercise its rights and obligations pursuant to this Section 5 (“Repurchase Notice”); provided, however, that upon the occurrence of any Call Event, the Company shall advise the Executive Stockholder Entities as to whether it intends to deliver a Repurchase Notice, whether the purchase price will be less than the Fair Market Value (if applicable), and in respect of which Options or Stock, within thirty (30) days following the date of such Call Event. Notwithstanding the foregoing, the Company reserves the right to extend the Call Period to ensure that the Executive Stockholder Entities are able to comply with the one hundred and eighty (180) day stock ownership holding period identified in Section 5(e) below, but which shall in no event extend beyond thirty (30) days after the date that such one hundred and eighty (180) day holding period expires. The completion of the purchases pursuant to the foregoing shall take place at the principal office of the Company no later than the fifteenth business day after the giving of the Repurchase Notice. The applicable Repurchase Price (including any payment with respect to the Options as described in this Section 5) shall be paid by delivery to the applicable Executive Stockholder Entities of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Executive Stockholder Entities (or by wire transfer of immediately available funds, if the Executive Stockholder Entities provide to the Company wire transfer instructions) against delivery of certificates or other instruments representing the Stock so purchased and appropriate documents canceling the Options so terminated, appropriately endorsed or executed by the applicable Executive Stockholder Entities or any duly authorized representative, if such Stock or Options are held in certificated form. For the avoidance of doubt, in the event that the Company does not exercise its rights pursuant to this Section 5(d) as to any Stock, the Executive Stockholder Entities’ ownership of and rights in such Stock shall not be affected.

(e) Use of Note to Satisfy Call Payment; Termination of Call Right. Notwithstanding any other provision of this Section 5 to the contrary, if there exists and is continuing any Event, the Company will, to the extent it has exercised its rights to purchase Stock or Options pursuant to this Section 5, in order to complete the purchase of any Stock or Options pursuant to this Section 5, deliver to the applicable Executive Stockholder Entities (i) a cash payment for any amounts payable pursuant to this Section 5 that would not cause an Event and (ii) a note having the same terms as that provided in Section 4(c) above with a principal amount equal to the amount payable but not paid in cash pursuant to this Section 5 due to the Event. Notwithstanding the foregoing, if an Event exists and is continuing for one hundred and eighty (180) days from the date of the Call Event, the proposed repurchase of that portion of the Stock and Options to be repurchased by the Company from the Executive Stockholder Entities pursuant to this Section 5 with the note described in the foregoing sentence shall immediately terminate, the Stock or Options shall be returned to the Executive Stockholder and the Company shall have no further rights or obligations under this Section 5. The occurrence of an Event shall toll, for any Options or Stock called pursuant to this Section 5, any time period requirements for (x) exercise by the Executive Stockholder or (y) for their termination.

(f) Expiration of this Section 5; Company’s Election. Notwithstanding anything in this Agreement to the contrary, except for any payment obligation of the Company which has arisen prior to the occurrence of a Lapse Date, this Section 5 shall terminate and be of no further force or effect upon the occurrence of such Lapse Date. The Company may only exercise its call option pursuant to a Call Event for one hundred and eighty (180) days after such event. The rights of the Company set forth in this Section 5 are exercisable in the sole discretion of the Company, and the Executive Stockholder acknowledges and agrees that the Company is under no obligation to, and may determine not to elect to, exercise such rights.

(g) Effect of Accounting Principles. Notwithstanding anything set forth in Section 4 or 5 to the contrary, in the event that it is determined by the Board, after consultation with the Chief Financial Officer of the Company, that any of the provisions of either of Section 4 or 5 would result in any of the Options being classified as a liability as contemplated by Financial Accounting Standards Board Accounting Standard Codification (ASC) Section 718, Compensation — Stock Compensation (FASB ASC 718), including any amendments and interpretations thereto, then the Company shall be required to advise the Executive Stockholder Entities of this determination (x) in order to allow the Executive Stockholder Entities to exercise their rights under Section 4 and (y) in order for the Company to exercise its rights under Section 5 (but only to the extent that the Company notifies the Executive Stockholder Entities of its intent to exercise its rights under Section 5), and then in any such case the following terms shall apply:

(i) any shares of Stock that are to be purchased by the Company pursuant to Section 4 or 5, as applicable, may only be so purchased if and when such shares have been held by the applicable Executive Stockholder Entities for at least six months (or such lesser period as is determined necessary by the Company’s accountants to avoid liability accounting); and

(ii) with respect to any exercisable Options, upon the occurrence of the applicable event identified in Section 4 giving rise to the Executive Stockholder’s rights thereunder or a Call Event, the Executive Stockholder Entities may be required by the Company to elect, in accordance with the terms of the relevant Award Agreement, to receive from the Company, on one occasion, in exchange for all of the exercisable Options then held by the applicable Executive Stockholder Entities, if any, a number of shares of Stock equal to the quotient of (x) the product of (A) the excess, if any, of the Fair Market Value over the Option Exercise Price and (B) the number of shares then acquirable on exercise, divided by (y) the Fair Market Value, which Options shall be terminated in exchange for such payment of shares of Stock (any such shares of Stock so acquired, the “Net Settled Stock”).

(b) If the Company becomes subject to the reporting requirements of Section 12 of the Exchange Act, the Company will file the reports required to be filed by it under the Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder, to the extent required from time to time to enable the Executive Stockholder to sell shares of Stock, subject to compliance with the provisions hereof without registration under the Exchange Act within the limitations of the exemptions provided by (A) Rule 144 or (B) any similar rule or regulation hereafter adopted by the SEC.

8. “Piggyback” Registration Rights. Upon the execution of this Agreement:

(a) The Parties agree to be bound by all of the terms, conditions and obligations and receive all rights of the Registration Rights Agreement (the “Registration Rights Agreement”) as they relate to the exercise of piggyback registration rights as provided in Sections 4, 5, 6, 7, 8 and 11 and the corresponding definitions in Section 1 (but not Sections 11(a) and 11(l)) of the Registration Rights Agreement entered into by and among the Company and investors party thereto (the “Piggyback Registration Rights”), as in effect on the date hereof (subject, with respect to any such Executive Stockholder provided Piggyback Registration Rights, only to any amendments thereto to which such Executive Stockholder has agreed in writing to be bound), and, if any of the Investors are selling stock, shall have all of the rights and privileges of the Piggyback Registration Rights (including, without limitation, the right to participate in the Initial Public Offering and any rights to indemnification and/or contribution from the Company and/or the Investors), in each case as if the Executive Stockholder were an original party (other than the Company) designated as a “Shareholder” to the Registration Rights Agreement, subject to applicable and customary underwriter restrictions; provided, however, that at no time shall the Executive Stockholder have any rights to request registration under Section 3 of the Registration Rights Agreement; provided, further, that in lieu of the Executive Stockholder exercising the Piggyback Registration Rights in connection with any Public Offering in which such rights would otherwise be available, the Board may, in its sole discretion, elect to offer the Executive Stockholder a waiver of the restrictions on transfer contained in Section 3(a) with respect to the number of shares of Common Stock that would have been subject to such Piggyback Registration Rights in connection with such Public Offering (a “Transfer Restriction Waiver”), which Transfer Restriction Waiver may be accepted or rejected

by the Executive Stockholder in his sole discretion (but which Transfer Restriction Waiver offer shall not in any way limit the Executive Stockholder’s Piggyback Registration Rights should he choose to exercise them) (any Common Stock subject to a Transfer Restriction Waiver, the “Waiver Stock”). All Stock purchased or held by the applicable Executive Stockholder Entities pursuant to this Agreement shall be deemed to be “Registrable Securities” as defined in the Registration Rights Agreement except for Waiver Stock. Effective after the occurrence of an Initial Public Offering, if any of the Investors are selling stock in a circumstance in which the Executive Stockholder would not have Piggyback Registration Rights (other than in connection with a Transfer Restriction Waiver), the restrictions on transfer contained in Section 3(a) shall be waived with respect to the number of shares of Common Stock that would have been subject to such Piggyback Registration Rights if such sale by the Investors had resulted in the Executive Stockholder having Piggyback Registration Rights.

(b) In the event of a sale of Common Stock by any of the Investors in accordance with the terms of Sections 3 or 4 of the Registration Rights Agreement, unless the Board shall have determined to effect a Transfer Restriction Waiver and Executive shall have accepted such Transfer Restriction Waiver, in which case the provisions of Section 8(h) shall apply, the Company will promptly notify the Executive Stockholder in writing (a “Piggyback Notice”) of any proposed registration (a “Proposed Registration”), which Piggyback Notice shall include: the principal terms and conditions of the proposed registration, including (i) the number of the shares of Common Stock to be sold, (ii) the fraction expressed as a percentage, determined by dividing the number of shares of Common Stock to be sold by the holders of Registrable Securities by the total number of shares held by the holders of Registrable Securities selling the shares of Common Stock, (iii) the proposed per share purchase price (or an estimate thereof), and (iv) the proposed date of sale. If within fifteen (15) days, in the case of a sale pursuant to Section 3 of the Registration Rights Agreement, or within five (5) days, in the case of a sale pursuant to Section 4 of the Registration Rights Agreement, of the receipt by the Executive Stockholder of such Piggyback Notice, the Company receives from the applicable Executive Stockholder Entities of the Executive Stockholder a written request in a form acceptable and in conformity with Section 21 of this Agreement (a “Request”) to register shares of Stock held by the applicable Executive Stockholder Entities (which Request will be irrevocable unless otherwise mutually agreed to in writing by the Executive Stockholder and the Company), shares of Stock will be so registered as provided in this Section 8; provided, however, that for each such registration statement only one Request, which shall be executed by the applicable Executive Stockholder Entities, may be submitted for all Registrable Securities held by the applicable Executive Stockholder Entities.

(c) The maximum number of shares of Stock which will be registered pursuant to a Request will be the lowest of the amounts determined in accordance with (i), (ii) or (iii) below:

(i) the sum of the Banked Shares plus the amount determined by multiplying the number derived in accordance with (1) below by the number derived in accordance with (2) below:

(1) the difference between (A) the number of shares of Stock then held by the Executive Stockholder Entities, including all shares of Stock which the Executive Stockholder Entities are then entitled to acquire under unexercised Options to the extent then exercisable minus (B) the Banked Shares minus (C) the Waiver Stock, and

(2) a fraction, the numerator of which is the aggregate number of shares of Stock being sold by holders of Registrable Securities and the denominator of which is the difference between the aggregate number of shares of Stock owned by the holders of Registrable Securities minus the Waiver Stock; or

(ii) the maximum number of shares of Stock which the Company can register in connection with such Request in the Proposed Registration without adverse effect on the offering in the view of the managing underwriters (reduced pro rata as more fully described in subsection (d) of this Section 8); or

(iii) the maximum number of shares which the Executive Stockholder (pro rata based upon the aggregate number of shares of Stock the Executive Stockholder and all Other Employee Stockholders have requested to be registered) is permitted to register under the Piggyback Registration Rights.

For purposes of this Agreement, the “Banked Shares” shall mean, with respect to the Executive Stockholder Entities, a number of shares equal to the difference between (x) the aggregate number of shares of Stock which the Executive Stockholder Entities could have sold in connection with the exercise of their Piggyback Registration Rights in all registrations giving rise to Piggyback Registration Rights of the Executive Stockholder Entities, whether contractual or voluntarily extended to the Executive Stockholder Entities pursuant to this Section 8, to the extent provided herein occurring on or after April 18, 2013 (collectively, the “Prior Registrations”) if such Executive Stockholder Entities had exercised their Piggyback Registration Rights in full in connection with the Prior Registration minus (y) the aggregate number of shares of Stock sold by the Executive Stockholder Entities in all such Prior Registrations

(d) If a Proposed Registration involves an underwritten offering and the managing underwriter advises the Company in writing that, in its good-faith opinion, the number of shares of Stock requested to be included in the Proposed Registration exceeds the number which can be sold in such offering, so as to be likely to have an adverse effect on the success of such offering, then, unless the managing underwriter advises that marketing factors require a different allocation, the Company will include in the Proposed Registration:

(i) with respect to a sale pursuant to Section 3 (other than a sale subject to the second paragraph of Section 4(a) of the Registration Rights Agreement) and Section 4(c) of the Registration Rights Agreement: first, 100% of the shares of Stock of the selling holders of Registrable Securities either requesting such Demand Registration (as defined in the Registration Rights Agreement) or delivering the Take-Down Notice (as defined in the Registration Rights Agreement), as the case may be; second, to the extent of the number of shares of Stock requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without

having the adverse effect referred to above, the number of shares of Stock which the selling holders of Registrable Securities, the Executive Stockholder and all Other Employee Stockholders and any other Persons who are entitled to piggyback or incidental registration rights in respect of Stock pursuant to this Agreement or pursuant to Other Employee Stockholders Agreements (together, the “Holders”) have requested to be included in the Proposed Registration, such amount to be allocated pro rata among all requesting Holders on the basis of the relative number of shares of Stock requested to be included in such Proposed Registration by such Holders (including upon exercise of all exercisable Options); and (iii) third, all other shares of Stock requested to be included in such Proposed Registration, including any securities requested by the Company; or

(ii) with respect to a sale pursuant to Section 4 (other than Section 4(c)) of the Registration Rights Agreement: first, 100% of the shares of Stock the Company proposes to sell; (ii) second, to the extent of the number of shares of Stock requested to be included in such registration which, in the opinion of such managing underwriter, can be sold without having the adverse effect referred to above, the number of shares of Stock which the Holders have requested to be included in the Proposed Registration, such amount to be allocated pro rata among all requesting Holders on the basis of the relative number of shares of Stock requested to be included in such Proposed Registration by such Holders (including upon exercise of all exercisable Options); and (iii) third, all other shares of Stock requested to be included in such Proposed Registration.

(e) Upon delivering a Request, the Executive Stockholder having Piggyback Registration Rights pursuant to Section 8(b) will, if requested by the Company, execute and deliver a custody agreement and power of attorney having customary terms and in form and substance reasonably satisfactory to the Company with respect to the shares of Stock to be registered pursuant to this Section 8 (a “Custody Agreement and Power of Attorney”). The Custody Agreement and Power of Attorney will provide, among other things, that the Executive Stockholder will deliver to and deposit in custody with the custodian and attorney-in-fact named therein a certificate or certificates (to the extent applicable) representing such shares of Stock (duly endorsed in blank by the registered owner or owners thereof or accompanied by duly executed stock powers in blank) and irrevocably appoint said custodian and attorney-in-fact as the Executive Stockholder’s agent and attorney-in-fact with full power and authority to act under the Custody Agreement and Power of Attorney on the Executive Stockholder’s behalf with respect to the matters specified therein.

(f) The Executive Stockholder agrees that he or she will execute such other reasonable customary agreements as the Company may reasonably request to further evidence the provisions of this Section 8, including reasonable and customary lock-up agreements, provided, that such lock-up agreement, including any lock-up agreement executed pursuant to, and subject to the terms of, Section 5 of the Registration Rights Agreement, will explicitly exempt and exclude any transaction between the Executive Stockholder and the Company pursuant to Section 4 or Section 5 of this Agreement.

(g) Notwithstanding Section 11(l) of the Registration Rights Agreement, this Section 8 will terminate on the earlier of (i) the occurrence of a Change of Control and (ii) with respect to the Executive Stockholder, on date on which the Executive Stockholder ceases to own any Registrable Securities.

(h) If the Board shall have elected to offer the Transfer Restriction Waiver in lieu of Piggyback Registration Rights, and the Executive Stockholder shall have accepted such waiver, all in accordance with Section 8(a), the Company will notify the Executive Stockholder on or promptly following the completion of the Public Offering giving rise to the Transfer Restriction Waiver which notice shall include: (A) the number of shares of Common Stock sold by the Investors in such Public Offering and (B) the number of shares of Stock to which the waiver of transfer restrictions shall apply. For the avoidance of doubt, the provisions in Section 5 of the Registration Rights Agreement will apply to such shares of Stock notwithstanding the Transfer Restriction Waiver.

(i) Notwithstanding Section 11(a) of the Registration Rights Agreement, the provisions of this Section 8, as they relate to the piggyback registration rights of the Executive Stockholder, shall only be amended or waived in accordance with Section 15.

9. Additional Rights of Executive Stockholders. Prior to the consummation of the Initial Public Offering, if the Company issues Common Stock in a transaction in which the Investors would be entitled to preemptive rights and within 90 days following the consummation of such issuance the Executive Stockholders so request, the Board, in its sole discretion, will consider in good faith offering the Executive Stockholders the opportunity to purchase additional shares of Common Stock.

10. Rights to Negotiate Repurchase Price. Nothing in this Agreement shall be deemed to restrict or prohibit the Company from purchasing, redeeming or otherwise acquiring for value shares of Stock or Options from the Executive Stockholder, at any time, upon such terms and conditions, and for such price, as may be mutually agreed upon in writing between the Parties, whether or not at the time of such purchase, redemption or acquisition circumstances exist which specifically grant the Company the right to purchase, or the Executive Stockholder the right to sell, shares of Stock or any Options under the terms of this Agreement; provided that no such purchase, redemption or acquisition shall be consummated, and no agreement with respect to any such purchase, redemption or acquisition shall be entered into, without the prior approval of the Board.

11. Notice of Change of Beneficiary. Immediately prior to any transfer of Stock to an Executive Stockholder’s Trust, the Executive Stockholder shall provide the Company with a copy of the instruments creating the Executive Stockholder’s Trust and with the identity of the beneficiaries of the Executive Stockholder’s Trust.
